# Description and specifications:
The lens is convex on one side. The metal housing has an M27 thread on one end and keyholes on the other. It could be the tube lens, maybe part of the condenser, maybe the rear of the lens, maybe the lower element from the head, or something else entirely. I don't know the manufacturer either, but if someone recognizes it from the font or number, please contact me :)
